Tóm tắt

 The initial hydrothermal treatment parameters did not achieve the proposed objective of this effort
  the reduction of intrinsic ash in the corn stover. However, liquid fractions from the 170�C treatments was indicative that some of the elements routinely found in the ash that negatively impact the biochemical conversion processes had been removed. After reviewing other options for facilitating ash removal, sodium-citrate (chelating agent) was included in the hydrothermal treatment process, resulting in a 69% reduction in the physiological ash. These results indicated that chelation ?hydrothermal treatment is one possible approach that can be utilized to reduce the overall ash content of feedstock materials and having a positive impact on conversion performance.
